Ive replaced all the filters on my RO unit including the membrane and the two DI filters. The membrane is 100gpd just like the old one. I've checked for kinks in the hoses. My "good" water flow seems to have decreased quite a bit and my waste water seems to be the same amount. Is it normal for a RO unit to have less "good" water flow right after the filters were replaced? I have enough flow going in from my sink because it worked just fine before I replaced the filters. I am just wondering if this is normal.
